Hi again. I'm having another splash screen problem.

I have 3 forms namely login, main, splash. Once the user has authenticated himself, the main functions will be started and the splash screen is shown as well. My problem is that if the user moves or minimizes the splash screen, the main form is shown. I also tried setting the windowstate of the main form to minimized but another problem is that it can just be clicked on the taskbar and it will be in plain view again. How do I code this such that the main form will only be visible once certain variables are set and the splash is closed?

Currently, I am using these codes:

On the login screen(after checking the username and password with the database):

main.show

On the main screen:

Private Sub Form_Load()
      Call CameraOn()
      splash.show
      End Sub

I plan to have a timer control on the splash form with the following code. loadokay is my Boolean trigger for the splash to disappear. It is triggered if all preparations in the main form are complete.

If (main.loadokay=True) Then 
splash.hide 
main.show 
End If

However, this is no use if the main form can just be activated anytime or the splash screen can be moved aside or minimized.

In the design time, you must make your form Splash Border Style property to None so it cant be moved out or minimized. You can also show your splash as modal window like this

splash.show vbModal, Me

But make sure you have a timer event make your splash form unload automatically, or unload when user click on the splash screen form.

Happy coding...

Set your form Movable property to False on Design time.

You can also add this code to your form keypress event.

KeyAscii = 0

This will disable all keys from the keyboard (even mouse - not so sure). And yes, you should use a timer control.

Thank you for your help. All I needed was the modal window addition. Thanks again.

dont know why you've given me -1 for my solution. Use your brain to think and use your eyes to read the solutions!

On second thought, vbModal is okay but it interferes with my mouse clicks. The mouse moves and clicks I execute on the main form are not performed because of the splash screen.

Put your code on the login form.

Example:

Splash.Show vbModal, Me

Then on your splash form after the timer control time is over (?),

Me.Hide

There is a much easier way. Set your splash screen AND Main form properties as such -

MaxButton = False
MinButton = False
Moveable = False

Now add the following code that will disable the "x"/close button. This way the splash will show and can not be minimised, closed, moved or nothing. It will only happen once all events is done in your main form.:)

In a module, add the following code -

Option Explicit

In your form, call it as in -

Call MenuRemoveClose(Me)

Put your code on the login form.
Example:

Splash.Show vbModal, Me

Then on your splash form after the timer control time is over (?),

Me.Hide

Thanks but I get an error if I use this code.
Run time error -2147024726 (800700aa)

End Sub

In your form, call it as in -

Call MenuRemoveClose(Me)

Thanks for the module. Now the splash can't be closed. However, the mouse move codes of the main form are executed on the splash form. It seems that the mouse move and mouse click functions are executed on the objects on screen and not on the form. Is there any other way to solve this? Thanks.

Yes, set both form properties - "KeyPreview to true until all the code ran.

Hi Andre,

Code still does not work after setting keypreview. I see the mouse being moved and clicked on the splash form. When it is unloaded, the main form shows that it was not clicked and modified at all.

I helped another member here about 2 weeks ago. See if you can find the post about keydown events on a form. I gave him all the sample code he needed to get the form mouse move events.:)

Another question, why don't you just load all the start up code on the splash screen and then show the main form?

I'll start looking for it. :)

About loading the code on the splash screen, I was planning on doing it but I don't think it will work with the mouse clicks(its really a pain). Given the code I found, I'm about certain that it will just click whatever is on screen. If I hide the main form with a splash screen, it just clicks the splash.

http://www.vb6.us/tutorials/move-mouse-api - the code I mentioned last time.

If you find the code (about a week or 2 back) you will see that all mouse events is caught and send to a form, whether it is on a form or just the screen, no matter.;)

Is it this one?
DataList & Mouse scroll

That sounds like a better code. :)


Edit: Can't seem to find anything else that is related to keydown events. Checked your last posts about up to 18 days back.

Nah, I'll find it tomorrow Martin and help out with the solution. I'm "sat"/tired, going home now.:)

I couldn't find the link, but the code below should solve your problem. Adjust it to suit your needs -

Option Explicit

Private Type POINTAPI
    X As Long
    Y As Long
End Type

Private Declare Function GetCursorPos Lib "user32" _
(lpPoint As POINTAPI) As Long

'***********************
'THESE TWO FUNCTIONS RETURN THE POSITION ON THE SCREEN
'IN PIXELS, OF THE CURSOR

'EXAMPLE USAGE:

'Private Sub Form_MouseMove(Button As Integer, _
     'Shift As Integer, X As Single, Y As Single)

'    Label1.Caption = "X Screen Position = " & GetXCursorPos
'    Label2.Caption = "Y Screen Position =  " & GetYCursorPos
'End Sub
'***********************************

Public Function GetXCursorPos() As Long
   Dim pt As POINTAPI
   GetCursorPos pt
   GetXCursorPos = pt.X
End Function

Public Function GetYCursorPos() As Long
   Dim pt As POINTAPI
   GetCursorPos pt
   GetYCursorPos = pt.Y
End Function

Hi Andre,

I think it is better to show you what I mean. I have uploaded a sample program which depicts the problem.

I don't know why the splash screen is not on top anymore in this sample program though. In my original program, it is always on top. Hope you understand what I mean.

Thanks,
Martin

Thanks Andre.

@all,
Just bumping the thread. Has anyone tried out the project I attached? Thanks.
